for Dorset County Council

The site encompasses the lower reaches of the River Avon and its flood plain between Bickton and Christchurch. The River Avon displays wide fluctuations in water level and parts of the valley are regularly flooded in winter. The Avon valley has a greater range of habitats and a more diverse flora and fauna than any other chalk river in Britain. The valley includes one of the largest expanses of unimproved floodplain grassland in Britain, including extensive areas managed as hay meadow.

This bridge replacement contract is situated on the River Avon flood plain, northwest of Sopley. The site is designated a special area of conservation (SAC), of special scientific interest (SSSI) and nature conservation interest (SNCI); it is a wetland of international importance (RAMSAR) and candidate special protection area (SPA). The existing structure was demolished and replaced with a 38 metre 5 span composite steel beam/reinforced concrete bridge deck founded on 500mm Ø driven tubular piled abutments.
